I run a Bert...and I've had extremely good luck with it....But a Brinn is by far easier to rebuild...But I think they are both nice pieces...Bert seems to be more on the new design stuff, while Brinn they just kinda set back...They maybe actually getting behind...That Ball spline deal and the new hubs and axels are SWEEEET from Bert

THE BALL SPLINE IS NICE BECAUSE OF HOW THE TAILSHAFT IS MADE INTO THE HOUSING WITH THE FRONT YOKE. FOR INSTANCE IF YOU WERE TO BREAK A TRAILING ARM THE DRIVESHAFT WON'T COME OUT. OTHER THAN THAT THE BRINN IS NICE TOO.

Reliability doesn't seem to be an issue with either tranny. If you have a rear suspension that moves around alot like a four link LM then a Bert ball spline would be worth the extra money. If you're currently running a stock tranny a Brinn is the same length so you can use the same length driveshaft.

The Brinn uses much simpler shifter setup and shorter driveshaft.

It all has to do with where the driveshaft mounts to the tranny. Normally a driveshaft runs inside a bushing creating friction and limits the movement to the lenght of the splined portion of the yoke's input shaft. With a ball spline it replaces the standard tailstock of the tranny and the input shaft (yoke) is mounted to the tailstock that consists of a ball spline like ball bearings inside of a rounded track that run much smoother with less friction and has alot more travel than the standard setup which is great for the 4-link cars where the rearend movement is so extreme you don't have to worry about pulling the driveshaft out or the yoke slaming into the tailstock
